Q: Join() equivalent function for F# sequences

I am porting C# code to F# that makes use of LINQ's Join() extension method. Just as I use that in method call chains, I would of course like to have an F# function to pipe into. However, there is no equivalent in the Seq module, and while the same result could also be achieved with a nested lamb...

erk. Should ThreadFactory run the task on the created Thread or just return a new Thread?

@DanPantry should return new threads

as far as I'm aware

Dan Pantry

@skiwi: awesome :) Thanks

Just doing something so hacky I could potentially cut a tree with it

Well, not hacky, but yeah

skiwi

private final static ScheduledExecutorService service = Executors.newScheduledThreadPool(1, DocumentEntry::daemonThread);

private static Thread daemonThread(final Runnable runnable) {
    Thread thread = new Thread(runnable);
    thread.setDaemon(true);
    return thread;
}

Example ^

Dan Pantry

ah, yup, this won't work, derp

/**
 * Create a BasicScheduler that will execute all of it's tasks on
 * the given thread.
 * @param thread
 */
public BasicScheduler(Thread thread) {
	// So hacky I could cut a tree with it.
	this(Executors.newSingleThreadScheduledExecutor(new ThreadFactory() {
		@Override
		public Thread newThread(Runnable r) {
			return thread;
		}
	}));
}

hopefully you can understand what i was trying to achieve there

skiwi

4:59 PM

You would want to use lambdas ;)

but honestly, I don't

if you were extending something, then you'd need a super(...) call

Dan Pantry

Lambda didn't seem to want to play ball, there

Nah the idea is that I have this Scheduler interface which funnily enough schedules tasks

However I want to create a Scheduler that allows me to execute all tasks scheduled on the current thread

though in hindsight perhaps that complexity isn't needed

Simon André Forsberg

@DanPantry make the Thread argument final and it would work, although I can't recommend it... wtf are you trying to do?

Dan Pantry

@SimonAndréForsberg i'll make a gist to try and show what i'm trying to do 1 second

@SimonAndréForsberg

also, ignore the displayWindow.update() call, I've changed that because boy taht was stupid

Simon André Forsberg

@DanPantry What is the Scheduler class?

Dan Pantry

5:08 PM

@SimonAndréForsberg gist.github.com/DanPantry/cf7205f40df27e7bc964 updated it for you

Disposable is also included because you'll probably ask about that :p

Simon André Forsberg

@DanPantry Sounds like you want a ExecutorService executor = Executors.newXXXX

Dan Pantry

@SimonAndréForsberg funny you mention that, because that's the implementation BasicScheduler uses under the hood

@SimonAndréForsberg (whcih is the concrete implementation of Scheduler). I've added that to the gist too

Simon André Forsberg

@DanPantry So... you want a scheduler that runs the tasks on the current thread??

> the Scheduler would run on the Main thread and prevent the program from immediately returning.

Dan Pantry

@DanPantry I basically realized here that it's not neceessary

Oh balls that's not what I meant to do. but yeah. I don't think it's necessary any more because i can just, you know, invoke the methods normally.

@Dmitri There aren't any clear closing guidelines for public beta. Private Beta closures come as a result of insufficient performance during a small time period of less than a month. We don't have such an easy metric for public, as it more happens that we spend months looking into a site and trying everything we can to make sure it doesn't close. Think of three routes - a growing beta eventually graduates, a stagnant beta sits in beta, and a dying beta may close. What qualifies as dying rather depends on the site though, but largely starts from "not enough community backing." — Grace Note ♦ Dec 17 '13 at 14:00

Simon André Forsberg

@Jamal besides, we already have formatting

nhgrif

formatting and code-formatting are not the same. The former should probably refer to formatting output or something like that. Otherwise, it's a meta-tag.

Simon André Forsberg

@Mat'sMug I'd say we're a growing one

Mat's Mug

then enough already.

@nhgrif Yeah, I know I probably won't run

Simon André Forsberg

@syb0rg Whether or not I will run will depend on if I feel I have the time or not

Mat's Mug

I just find it quite annoying that everywhere on SE/MSE when a beta site doesn't graduate it's either because it's stagnating or on its way to closure. That doesn't encourage new users to start investing their time on this site to gather rep that might just evaporate.

"but we're special"

I know I probably won't have the time. Plus there are way more qualified people than me.
